DKD Series Diaphragm Product Data Sheet

< STANDARDS > IPEX DKD Series Diaphragm Valves are ultra-compact, direct acting pneumatic valves. The DKD diaphragm is suitable for shutting off very dirty and highly viscous fluids. The internal geometry of the body optimizes fluid dynamic efficiency by increasing the flow rate. The valve is comprised of three elements: the body, diaphragm and sealing ASTM D1784 bonnet. When compressed air enters the bonnet, the diaphragm is ASTM D1785 pressed against the body’s weir, interrupting the flow. This simplified ASTM D2466 ASTM D2467 operating principle and the lower number of components guarantees ASTM D2464 high reliability and durability. The DKD Series Diaphragm Valves are ASTM F1498 part of our complete systems of pipe, valves, and fittings, engineered and manufactured to our strict quality, performance and dimensional standards.

Flow Coefficients

The flow coefficientV (C ) represents the flow rate in gallons per minute (GPM) at 68°F for which there is a 1 psi pressure drop across the valve in the fully open position. These values are determined from an industry standard testing procedure which uses water as the flowing media (specific gravity of 1.0). To determine specific flow rate and pressure loss scenarios, one can use the following formula:

Where, Q 2 f is the pressure drop (friction loss) in psi, f =sg x sg is the specific gravity of the fluid, C V Q is the flow rate in GPM, CV is the flow coefficient.

Flow Coefficient Correction Factor Use this chart to determine the appropriate flow coefficient correction factor depending on the amount of disc travel. As the valve cycles from fully open (100% travel) to fully closed (0% travel), the

corresponding CV value will decrease in accordance with the adjacent graph.

Accessories

Fastening and Supporting All valves, whether manual or actuated, must be adequately supported in many applications. The DKD series provides an integrated bracket that permits direct anchoring of the valve body without the need of other components. For wall or panel installation, dedicated PMDK mounting plates which are available as accessories can be used. These plates should be fastened to the valve before wall installation.

iv. Tighten both union nuts. Hand tightening is typically sufficient to maintain a seal for the maximum working pressure. Over-tightening may damage the threads on the valve body and/or the union nut, and may even cause the union nut to crack.

c. For flanged style, join both flanges to the pipe flanges. For correct joining procedure, please refer to the section entitled, “Joining Methods - Flanging” in the IPEX Industrial Technical Manual Series, “Volume I: Vinyl Process Piping Systems”.

3. Connect a suitable air supply and pilot system to the actuator. Be sure to check that both the working and control pressure are in accordance with the specifications. 4. If anchoring is required, fix the valve to the supporting structure using the mounting holes on the bottom of the valve body.
